Brake Light Switch: Testing and Inspection

STOP LAMP SWITCH CHECK





Connect a circuit tester to the stop light switch, and check whether or not there is continuity when the plunger of the stop lamp switch is pushed in and when it is released. The stop lamp switch is in good condition if there is no continuity when the plunger is pushed in to a depth of within 4 mm (0.16 inch) from the outer case edge surface, and if there is continuity when it is released. For vehicles with auto-cruise control system, the check for continuity should be made at connectors "a" and "b" of the stop lamp switch.
